MATTI-IIAS BROOK, 0F BOSTON, MASSACHUSETTS, ASSIGNOR TO UNITED SHOEMACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

END-LASTING MECHANISM.

Application filed July 25, 1910. Serial No. 573,706.

To all whom it may concern Be it known that I, MATTI-IIAS BROOK, acitizen of the United States, residing at Boston, in the county ofSuffolk and State of Massachusetts, have invented certain Improvementsin End-Lasting Mechanisms, of which the following description, inconnection with the accompanying drawings,

is a specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to end lasting mechanisms and particularly to endband supporting and actuating mechanism and it has for its object toprovide improved means for supporting and closing an end embracing bandand particularly for s0 closing the end portions of the band as toobtain suitable pressure thereof against the inner and less full side ofthe end portion of the shoe.

The invention is shown as embodied in a heel lasting mechanism but maybe applied without further development to a toe lasting mechanism.

An important feature of this invention is found in supporting mechanismfor the two ends of the band which is freely movable bodily in adirection transverse of the shoe. By this movement the end portions ofthe band are adjusted automatically to the positions of the adjacentsides of the shoe, this adjustment being laterally toward one side ofthe machine for a right shoe and toward the other side for a left shoe.This bodily adjustment is preferably, and as herein shown, made in aright line. This feature of the invention is herein embodied in amechanism which includes levers the inner ends of which are directedforwardly and inwardly and are connected to the band ends while thebackwardly and outwardly directed ends of the levers are connected bysprings to a relatively fixed support. These levers are fulcrumed uponthe front ends of forwardly actuated supports which serve first, throughthe levers, to tighten the band about the end of the shoe and then, bycarrying the fulcrums of the obliquely arranged levers forward after theforward movement of the inner ends of the levers have been arrested, toeffect inward pressure upon the band ends. In accordance with thisinvention in which the supports referred to are adjusted to the shape ofthe last the relation of'each lever to its support is the same as thatof the other lever to the support on which it is carried and thereforeuniform pressure is obtained at the two sides of the shoe. Byso-doingthe upper materials and particularly the end portions of theheel stilfeners are firmly clamped to the sides of the last on theinner, less full, side as well as at the outer side of the shoe. 'IVhenthis is done the lasting plates or wipers can draw the upper materialssnugly over the last edge and bottom and the finished shoe comes ofi thelast shaped to the clean-out contour of the last as is demanded" in fineshoemaking. As I am advised it is new with me'to provide a bandoperating mechanism having straight forwardly moving band endsupportsand having provision for adjustment to unsymmetrically positioned.lasts, and it is also new with me to provide a band operating mechanismhaving forwardly moving band supports which are automatically adjustablein right lines transversely of the machine for the purpose described.Novel mechanism embodying this part of the invention will'be laterdescribed.

A further feature of this invention which may be employed with orwithout the other features hereindisclosed consists in means foradjusting the supports forthe two ,band ends together for widths ofshoes. This may be employed also in accordance with this invention assupplemental band end closing means.

Still a further feature of this invention consists in means by which theoperator may apply band closing or upper tightening pressure to eitherend of the band as he may observe to be desirable at any time after theautomatic or other normal closing of the band has occurred. In thepreferred embodiment of the invention a lever has connections throughwhich one or the other, or one and then the other, end of the band maybe set up to clamp the work securely at the ends of the heel or the rearof the shank.

These and other features of the invention including important details ofconstruction will appear in connection with the following description ofone embodiment of the invention and will then be pointed out in theclaims.

Figure l is a perspective view of a heel lasting mechanism embodyingthis invention. Fig. 2 is a plan. Fig. 3 is a section on line 33, Fig.2.

The heel lasting mechanism herein shown as embodying the inventioncomprises a carriage or head portions of which are indicated at 2 towhich is connected the rear or closed portion of the heel band 4 by thestem 5, said band comprising as herein shown a flexible chain having anon-metallic lining and the stem 5 being extended rearwardly from aplate which is hinged at its upper end to the chain so that some freedomof movement is allowed to the band. The band has pivoted end plates 6which are hinged to the inner ends of levers 8 the outer ends of whichare connected by springs 10 to studs 12 on the head. The levers 8 arefulcrumed at 13 on the fronts of endwise sliding bars 14. These bars areherein shown as L shaped members the lateral or transversely extendingarms of which are overlapped by one another and provided with slots 16through which extend pins 18 rising from a cross head 19 on a plunger 20which it is contemplated shall be connected for operation to a cam shaftsubstantially as is the corresponding plunger in United States PatentNo. 521,954., The two L shaped members arranged as described form a Ushaped frame for supporting the front ends of the heel band and theslots 16 permit free bodily movement of the band end supportstransversely of the machine, thus allowing adaptation of the band endsto unsymmetrical position or formation of the end portion of the shoewhich is to be embraced. The forwardly directed arms of the L shapedmembers are connected by a right and left threaded screw 24 on which isa hand wheel 25 by which adjustment of said members, and therefore ofthe ends of the band, together may be made toward and from the medianline of the machine or from the shoe in the machine for adaptation towidths of shoes as also for compression or additional clamping of theupper materials against the sides of the last by the band ends. In thisadjustment the transverse arms of said members slide upon one anotherand relatively to the pins 18 as permitted by the slots 16. Thisarrangement renders the U-shaped frame inflexible or free from anylooseness or liability of movement of its parts relatively in the normaloperation of the machine. A yoke having arms 30 underlies the slide barsand these arms have upturned ends or shoulders located near the frontend of the slide bars and spaced apart a distance to permit unobstructedself-adjustment of the band end supports and band to different shoes aswell as adjustment by the hand wheel 25. This yoke is connected to avertical hand lever 32, fulcrumed on the head 2, by which it can bemoved in one direction to cause the upturned end to engage the slide baron the right side of the shoe or may be moved in the opposite directionto efiect engagement with the other slide bar. By this manual means theautomatic or self adjustment of the band to the position and shape ofthe last can be perfected if required and also supplemental band closingpressure can be applied to either band end alternatively. The usuallasting plates or wipers 40 are employed to close inover the top face ofthe band and over the shoe bottom to wipe over the innersole themarginal portion of the upper materials which have been clamped aboutthe end of the last by the band. The Wipers are actuated by link 42,cross head 43 and plunger 44 connection with a hand lever 45 and theirpath of closing movement is directed by cam slots 46 in the wipercarriers 48 to which the wiper plates are det-achably connected in wellknown manner. a

In the use of the machine a shoe is posi tioned with the heel end withinthe heel band and its toe end usually in operative relation to a toelasting mechanism. The band is then closed by force transmittedforwardly through the plunger 20, cross head 19, pins 18 and slide bars14 to the fulcrums of the levers 8. This carries the front ends of thelevers 8 (which are inclined inwardly and forwardly) forwardly until theband is tightened about the end of the last and then continued forwardmovement of the slide bars and of the fulcrum points 13 swings thelevers in the direction to force their inner ends and the ends of theband against the last inasmuch as the slide bars 14 are relatively rigidtransversely. The style of the last or its configuration for a right ora left foot may result in an unsymmetrical presentation of the shoe tothe band in which case there occurs automatically during this operationa self adjustment of the band end supporting means toward that side ofthe latch which is nearest the median line of the machine or which isleast full at the part engaged by the band end which is the regionadjacent to the end of the heel stiffener. This self adjustment orautomatic lateral movement of the band end supports is permitted and isguided and direct ed by the slots 16 which embrace the pins 18 on thecross head 19, and it is a right line movement of both slide barstogether in the same direction transversely of the machine. Thisadjustment for rights and lefts or unsymmetrical lasts occursautomatically and as it is a free and unrestrained movement will beefiected in whole or in large part during the initial tightening andclosing of the band and as a result of the described arrangement eachslide bar 14 and its connected lever 8 will occupy substantially thesame angular relation to one another and to the side of the shoe as isfound at the opposite side of the machine when the final end closingpressure comes on the band. This insures a uniformity of pressureagainst the two sides of the shoe which has heretofore been'secured in aless degree. For example if the slide bars were given a swinging orangular adjustment for rights and lefts instead of a right line movementthe angle formed by one bar and its lever 8 would be increased whilethat on the opposite side would be diminished and the stronger final endclosing pressure would then occur at the side where the smaller angle isformed which in practice is the fuller side of the shoe while the lessfull side is the one which, if either, should receive the strongestpressure.

After the automatic closing of the band above described as coming fromthe plunger 20 the hand wheel 25 which may previously have been used foradjustment for the width of the shoe, can he used to draw the slide bars14 tighter to effect further band end closing pressure at the two sidesof the shoe or the hand lever may be moved in one direction or the otherto set the band end up more snugly to the shoe at either side or at oneside and then the other, or repeatedly at a side requiring specialtreatment. When the band has been properly closed to clamp the uppermaterials firmly to the contour of the last throughout the length of theband and at the hollow inner side of the last as well as at the morefull outer side then the wipers are actuated to wipe the marginalportion of the upper above the band over upon the heel seat as shown inFig. 1.
